Full back protector!!

This price is awesome. I love how it extends more than the regular back protector.

Great fit !

I bought this full back protector for my Alpinestar Atem jacket. It fit perfectly into the big pocket on the back of the jacket. This is the most protective back protection insert I've ever seen. It's very light weight and flexible. I feel confident that it will provide protection in case of an accident. It cost slightly more than the other inserts, but I'm satisfied with the purchase.
